4 Claims.

This invention relates to an antenna and more particularly to an antennamounted on a motor vehicle.

An object of this invention is to provide an I antenna for a motorvehicle that may be reeled or rolled up when not in use.

Another object of this invention is to provide means that willfacilitate the reeling and unreeling of the antenna with a minimumamount of work and minimum amount of equipment.

Another object of this invention is to provide an antenna for a motorvehicle that has a plurality of leads or conductors that are notenclosed within the motor vehicle.

Another object of this invention is to provide an antenna for a motorvehicle that when in use is not enclosed within the motor vehicle andthat when not in use may be placed under shelter and hidden.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings, wherein a preferred embodiment of one form of the presentinvention is clearly shown.

In the drawings:

Fig. 1 shows a side elevation of an antenna extended or reeled ofi, asapplied to a motor vehicle.

Fig. 2 discloses a plan view of the antenna extended or reeled ofi.

Fig. 3 shows an end elevation of the reel with the antenna in the reeledposition.

Fig. 4 shows a sectional view of the reel as taken substantially on theline 44 of Fig. 5.

Fig. 5 is an end view of the reel viewed from the left of Fig. 4.

Fig. 6 is a fragmentary plan view of the reel.

Fig. 7 is a fragmentary view of the link engaging the free ends of theantenna.

Fig. 3 is drawn to a larger scale than Figs. 1 and 2.

Figs. 4, 5, 6 and 7 are drawn to a larger scale than the other figures.

In the drawings, the reference character 10 indicates the body of thecar provided with a sun visor 12.

Mounted immediately below the sun visor 12 is a reel 14 supported on thebrackets 16 and 18, insulatingly mounted on the body 10. One end of thereel 14 carries a stud 19 passing through the aperture 20 in the bracket16 and the other end of the reel carries a driving mechanism thatincludes a motor spring 22, having one end 24 fixedly secured to thereel 14 by a pin 26: andthe other end 28' fixedly attached to a spindle30, terminating in a rectangular portion 32, nonrotatably mounted in thebracket 18. The spindle 30 is rotatably journalled in the bearings 34and 36, carried by the reel 14 so that the reel 60. 14 may be rotatedwith respect to the spindle 32 as will appear more fully later. Atubular member 38 attached to the roll 14 by screws 39 and provided witha flange 40 holds the bearing 36 in a relatively fixed relation withrespect to the 5; reel 14.

A plurality of metallic conductors or cables, preferably made fromcopper, are attached to a metallic strip 44, carried by the reel 14 andextending substantially the entire length thereof. 7302 The other end ofthe leads 42 are carried by a link 46 provided with an eye 48 thatengages a hook 50, which may be attached to the cap of the radiator orany other part of the motor vehicle when the leads 42 are reeled off andhooked .75 on a suitable knob 52, carried by the body of the car whenthe antenna is in the reeled position as best seen in Fig. 3.

A lead or conductor 58 extending from the radio receiver mounted on themotor vehicle is atgal tached to a resilient contact member 60, carriedby the bracket 16, frictionally engaging an annular recess 62 of a cap64, attached to the reel 14 by the stud 19. The cap 64 is preferablysoldered to the metallic strip 44 at 66. 2

From the above description, it can be readily seen that upon thereleasing of the link 46 from the hook the motor spring 22, which isnormally in tension will rotate the reel 14, thereby winding theconductors 42 upon the reel so as to completely or substantially so hidethe antenna from View. When the antenna has been reeled the link 46 maybe hooked on the knob 52 so as to rigidly hold the link 46 in positionand so as to eliminate any undesirable noise caused '5; by the linkdangling. When it is desired to use the antenna, the link 46 may beremoved from position disclosed in Fig. 3, the conductors 42 reeled offand the link attached to the hook 50, thereby extending the antenna intoposition for mu use.

Although the antenna has been disclosed as being mounted under the sunvisor it can be mounted in any other suitable place, such as forexample, on top of the body, under the chassis or 1135 within the top.The modification disclosed is merely illustrative as any of the othersmay be used.

While the form of embodiment of the present invention as hereindisclosed, constitutes a pre- 1' 1.

ferred form, it is to be understood that other forms might be adopted,all coming within the scope of the claims which follow.

What is claimed is as follows:

1. An antenna for a radio mounted on a motor vehicle, comprising incombination, a resiliently biased reel attached to the motor vehicle, aplurality of conductors carried on said reel, means electricallyconnecting said conductors, said conductors being reeled ofi whenextended for use and hooked on said motor vehicle, the conductorsconverging towards the hooked point on said vehicle when extended foruse, and means for at all times connecting the antenna to the radioreceiver so as to impress signals thereon.

2. An antenna for a radio receiver mounted on a motor vehicle, saidmotor vehicle having a body carrying a sun visor, comprising incombination, a reel attached to the body under the sun visor, anelectrical conductor carried by the reel that may be wound on the reelwhen not in use as an antenna, means for connecting the conductor to theradio receiver so that signals picked up by the conductor are conductedto the radio receiver and an insulating member for attaching theconductor when extended to the radiator of the motor vehicle.

3. An antenna for a radio receiver mounted on a motor vehicle having atop, comprising a plurality of electrically connected conductors, saidconductors having one end insulatingly connected to one extremity of themotor vehicle and the other end attached to said top, said conductorsextending radially from said extremity to said top.

4. An antenna. for a radio receiver mounted in a motor vehicle having atop, comprising a reel insulatingly attached to said top, a plurality ofelectrically connected conductors, each having one end attached to oneextremity of the motor vehicle and the other end to said reel, saidconductors extending radially from said extremity to said reel.
